CC2340R5: About uniflash software burning problem

Part Number: CC2340R5
Other Parts Discussed in Thread: UNIFLASH

The chip I use is CC2340R5 PG2 version and uniflash 8.3.0. Now I have problems with production burning.

Question 1: When the whole chip is erased, I click the Verify Image button in the unifalsh software, and I get an error of -1274. But when I click the Load Image button, everything is burned normally. Why can't I use Verify Image to download the blank chip after the whole chip is erased?

Problem 2: The command line burning tool generated by the Generate Package will prompt CCFG sector (0x4E02000C) verification failure. The -1274 error will also be displayed when the burnt chip is blank
